Title: Rotation sensitive pressure regulator
Inventor: GIBSON D
IPC: F02D1/12
Filed: 1980-09-11
Abstract: Fuel delivery systems for combustion ignition engines and more particularly to devices for limiting exhaust smoke and/ or the rise in engine torque. When a compression ignition engine is operating at full speed and a load is applied to the engine, the engine speed decreases until a lug condition results. As the engine speed decreases, a greater volume of fuel is delivered to the combustion chambers resulting in an inherent increase in the output torque of the engine and in the production of smoke, the rotation sensitive pressure regulator (7) described herein solves these problems by using a movable spool valve (21a). Stability of the regulator (7) is also achieved by using a spring (40) that adjusts the static force applied to the spool valve (21a) and a nondeformable actuator member (19).

Title: Recovery of chlorinated poly(vinyl chloride)
Inventor: OLSON ALAN JAMES
IPC: B29B17/00
Filed: 1981-12-16
Abstract: A process for recovering chlorinated poly (vinyl chloride) ('CPVC') which is dissolved in liquid chlorine ('Cl2') to form a CPVC solution, CPVC is recovered by adding the CPVC solution to a halogenated lower alkane ('HLA'), which is simultaneously an excellent solvent for liquid Cl2, and a very poor solvent for CPVC. This peculiar property causes the CPVC to be precipitated from the three-component mixture as a finely divided solid with different morphological properties than if the HLA was added to the CPVC solution. The solid CPVC precipitated may then be separated from the solution of liquid Cl2 in the HLA. This solution of Cl2 in HLA is further separated into its component liquids, namely HLA and liquid Cl2 which are then each reused.

Title: Least squares method and apparatus for determining track eccentricity of a disk
Inventor: ESTES MARVIN FREDERICK
IPC: G11B21/10
Filed: 1988-08-31
Abstract: A transducer head (12), held in a fixed position as a preformatted disk (16) is rotated a full revolution, reads any sector address (30) accessible to the head. The addresses read come from a plurality of track revolutions (19) that depend on the magnitude of the eccentricity of the disk. A computer (52), programmed with a least squares algorithm, first coordinates (1) data corresponding to the angular position of the disk each time an address is read, with (2) data corresponding to the actual radius of each address. The computer then transforms the array of data coordinated into a sinusoidal track eccentricity compensating signal of the form D cos (wt + E) where the amplitude D is a constant computed from the least squares algorithm corresponding to the distance between the center of the disk and its rotational axis, the phase E, which is also a constant computed by least squares, corresponds to the angle the center of the disk is from an angular reference position, and wt is a variable equal to the product of disk angular speed and time.

Title: High-precision adjustable injection molding of single-mode fiber optic connectors
Inventor: BRIGGS PAUL RAYMOND JR
IPC: B29C45/26
Filed: 1990-08-07
Abstract: An injection-molded connector (10, 12, 14, 16) for single-mode optical fibers (22, 24) includes two mating plugs (12, 16) having aligned fiber-receiving holes. To keep transmission losses in the connector at an acceptable level, the eccentricity of each hole relative to its plug profile must be maintained within a fraction of a micron. In accordance with the invention, the mold utilized to form the plugs includes a dual-eccentric-cam adjustment mechanism that comprises nested conically shaped cams (40, 42). Rotation of the cams serves to move a part of the mold that positions a hole-forming pin (38). By means of this mechanism, the eccentricity of the fiber hole relative to the profile of the molded plug can be established and maintained within the required precision.
